Default Which prop valve and MC for ek rear disc swap?

Doing a rear disc swap on an EX EK... Rear swap is using 99-00 Si parts. Will a 15/16 MC bolt up with no mods? Which prop valve do I need? 4040 99-00 si?

Thanks!

This is the master I used on my EG hatch...didn't have to mod anything, but I'm not sure about the EK.

and I have a 40/40 prop valve...pedal feels awesome...

For prop valve information check out this LINK. Look at post #13, #18 and #20.

I'm going to be swapping rear discs from a Del Sol on my EG which has a 3030 prop valve. The EG Si has a 3040 prop valve and rear discs. For now I'm not going to change it based on those three posts.

The prop valve and MC are all the same factory specs and/or numbers. I put disks on my 99 DX as well as EX fronts, they're working fine with the stock PV and MC. From what I understand if you use Integra fronts it helps to use the Integra 1" MC since the piston in those calipers is bigger.

I completely flushed my system with DOT 4 which will probably be more helpful than swapping MC and prop valve.

Looks like he would recommend I change my MC but the OP should be fine.

You need at least a 7/8 MC and a prop valve is NOT needed unless you upgrade to bigger aftermarket calipers.

you CAN run a 13/16 MC, but eventually it MAY give out. Doesn't mean it wont work, it may last forever but I would upgrade the MC

What actually irked the crap out me was finding parking brake cables. Hopefully, I tracked down some that work and I'm putting them on tonight.

I finally go those parking brake cables on. They are DC sedan cables, the hatch probably would have worked but they are approx. 1/2" shorter.
